The Dolgin 4-Position Smart Battery Charger for JVC GYHM600/650 Cameras is a 4-position microprocessor-based battery charger. It provides fast, safe simultaneous charging of 7.2V SSL-JVC50 and similar batteries. This charger offers safe simultaneous charging of high capacity battery packs. All four batteries are ready in about 4.5 hours.
Dynamic Power Management (DPM) minimizes battery charge time. By dynamically adjusting battery charge current, more is allocated to the deeper discharged battery. Through this process the batteries are ready to use at about the same time.
